Method for generating corn ear panoramic image by using image sequence

Abstract

The invention provides a method for generating a corn ear panoramic image by using an image sequence, comprising the following steps: using a position-fixed digital camera to shoot the image sequence of a corn ear at a certain angel interval; extracting an image characteristic point, calculating motion parameters of adjacent two frame images in the image sequence according to the matched characteristic point, and registering the motion parameters to one coordinate system to compose a new image; searching a suture line in the new image, cutting the adjacent two frame images according to the position of the suture line and eliminating the pixel exposure difference at the two sides of the suture line by Gaussian template filtration; stretching the image at the horizontal and vertical directions to counteract perspective projection deformation; and sequentially performing the above operations on the image sequence to synthesize the corn ear panoramic image. The method of the invention can display the seamless splicing overall perspective of the image sequence of the corn ear on one new image, thus greatly reducing the redundancy of picture information, reducing information storage space and enabling the morphologic observation to be more visual.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method for generating a corn ear panorama by splicing image sequences. Background technique [0002] The outer shape of corn ears is an important index for reference in testing and breeding of new varieties. One of the best ways to record the appearance characteristics is to take images. Due to the cylindrical shape of the corn ear, one image often cannot record all the information, and only by taking multiple images around the ear can the entire surface be covered. In order to obtain the ideal observation effect, one ear usually needs 5-10 image records. There must be overlapping parts between multiple ear images, and these overlapping parts are difficult to distinguish with the naked eye, which will cause information redundancy and inconvenience for observation. [0003] Panoramic photography (panoramic photography) technology can be used to generate panoramas. Th...
